Proto-oncogenes are normal genes that play a role in cell growth and division. They can become oncogenes through mutations, which cause them to promote excessive cell growth and division, leading to cancer. The main difference between proto-oncogenes and oncogenes is that proto-oncogenes are normal, whereas oncogenes have undergone mutations that make them cancer-causing genes.

Is it true or false that only individuals with cancer have proto-oncogenes?

False. Proto-oncogenes are genes that can potentially become oncogenes, which are associated with cancer development. They are present in all individuals, not just those with cancer.


What do Proto-oncogenes regulate?

Proto-oncogenes stop cells dividing too often. When a mutation occurs to proto-oncogenes this is when cancer can occur, as there is then no hay-flick limit (normally cells have a limit to how many times then can divide) cells are able to replicate uncontrollably.
